Intelligent Traffic Management Control Method and System Using Vehicle Navigation System and High-Speed Internet Communication Network {Method for Control Intelligent Traffic Signal and System}

The present invention relates to a traffic management control method and system for achieving safety and management technology of a vehicle, a ship, an aircraft, and a vehicle navigation apparatus for realizing the system, and more particularly, to a vehicle of a vehicle driving on a road. ] Traffic control center that manages traffic signal controller in the two-way communication network between vehicle and signal, traffic control center that manages traffic control center, jurisdiction police station that manages traffic control department, jurisdiction police station The local police department and traffic signal controllers and signals are connected to the high-speed Internet communication network network in which a 1: 1 connection is made to the communication network or a broadband connection is made between the basic (1: 1) and multiple networks or between the basic and multi communication networks. Information on traffic information, analysis of collected information, and execution of judgment results. Implementing a control method and system, and correcting and clearly setting the position information in the vehicle position coordinate and geocoordinate correction device for implementing the system, and intelligently managing and operating traffic efficiency based on the clear position coordinate Implementing a system in which the traffic volume information of the vehicle is communicated in a one-to-one band between the vehicle and the signal signal, and broadly expanding the communication network with the bi-directional broadband between the vehicle and the signal signal. Based on the information collected by the control center, the traffic management department, the jurisdiction police station, the local police, the traffic signal controller device, and the signaling device in connection with the establishment of a high-speed Internet communication network network in which the basic communication connection is established between basic and multiple and multiple and basic. To control traffic signals more efficiently It relates to a vehicle navigation system and an intelligent traffic management control method and system using a high-speed Internet network that allows a safe and smooth traffic by management can be secured.

In general, roads developed from ancient times with human civilization, modernized from highway to modern automobile era, and advanced along with traffic signal system and operation method and system. There are only vertical and horizontal forms, and it is the central axis of the construction of industrial infrastructure that is important politically, economically, socially and culturally.

Roads are equipped with three-way intersections and higher intersections where roads meet or diverge, and multiple traffic lights are located near intersections for the purpose of cracking down or connecting traffic and pedestrians. A traffic signal controller is provided for turning on or turning off a signal for changing a signal of a plurality of traffic lights installed or blinking for a driver's attention.

The traffic signal controller controls traffic and direction of vehicles on roads, especially at intersections, and promotes pedestrian safety through crosswalks.

In the past, in order to efficiently operate a traffic signal, a yellow traffic light blinks at a traffic light at midnight to allow unprotected vehicle operation. However, even in this case, the vehicle must slow down or drive at a low speed near the crosswalk.

On the other hand, the traffic police sometimes manually control the operation of the traffic signal controller in order to control the amount of traffic in commuting time zones or frequent traffic jam areas where vehicles and pedestrians pass frequently.

Traffic signal controllers are installed around intersections or roads with crosswalks. The traffic signal controller is turned on, turned off or flashes at a set cycle in consideration of traffic volume at the installed location or various situations for traffic control. That is, the vehicle traffic lights are programmed to be linked with the pedestrian traffic lights installed in the crosswalk at the same time as the control for the straight or left turn or U-turn of the vehicle.

However, the traffic signal controller can control traffic effectively by controlling traffic signals in times of frequent traffic of vehicles or pedestrians, but inefficient operation of traffic or traffic of pedestrians is difficult. there was. That is, no pedestrians pass when the pedestrian traffic light of pedestrian crossing is lit green at night when there is little pedestrian traffic, but the vehicle to keep the traffic signal stops for a certain time in front of the pedestrian crossing and then departs when the traffic signal changes. Could. In addition, although the driver of the vehicle has a red traffic light, there are some cases in which there is a violation of the signal when there are no pedestrians crossing the crosswalk, so there is always a risk of a safety accident.

As a prior art, in the method and system for providing traffic and related information of Korean Patent Registration No. 10-0823210, it is possible to activate the real-time traffic data and related data in the past, the database for storing the past traffic data, the past for the mover profile Means for incorporating real-time and related traffic data to generate custom traffic predictions for the traveler profile, and means for sending personalized traffic predictions to the intended recipient, including estimated travel delays for the travel route described in the traveler profile. It is a system for providing traffic volume or related information, and this technology cannot implement an automation system that collects and connects information extensively using satellite network that can induce intelligent traffic signal controller.

In addition, the traffic data providing system using a mobile communication terminal of the Republic of Korea Patent No. 10-0624722 and its operation method is a traffic volume measuring the density of the mobile communication terminal in the cell by receiving the number of mobile communication terminals located in the cell from the mobile communication base station It comprises a measurement server, and a mobile communication terminal for receiving the density data from the traffic volume measurement server to display the traffic volume of the corresponding cell is not equipped with a separate device for providing traffic data, the cost is reduced, and the density data text As it is provided in the form of messages, it is not only easy to check the traffic volume data but also can share the traffic volume information with other users, which greatly improves the user's convenience, but fundamentally increases the traffic processing efficiency processed by using the collected traffic volume. There is no way to make it I like to be in contact with the vehicle then the amount of information was the situation of the problem is difficult to ensure the safety for the vehicle to pass the intersection with the semaphore because there is no way to deliver traffic information to follow the vehicle ahead.

In addition, the traffic accident black box configuration method and system of the Korean Patent Registration No. 10-823787 can be used to prove a mistake when an intersection accident occurs while providing accurate information for the driver to drive safely. Not only to perform the role of the recording device, but also to perform the conventional functions of navigation for the prevention of accidents, as well as the current information of the signal controller, the location information of the navigation, the speed information, and the distance information to prevent traffic accidents as much as possible. Based on the time information, camera image information and sound information, the driver who runs around the intersection can find out in advance how to solve the traffic accident at the intersection by using the acquisition information such as speed violation and signal violation. To prevent sudden stops, speeding and accidents. It is to provide information that can determine the mistake of the accident when a traffic accident occurs, including providing information on the safe operation to ensure that.

The prior art has been a patented technology for using the navigation system as a vehicle navigation device as a function of a black box to provide information for safe driving of a vehicle and to record and provide information on signal violations and accidents.

However, the prior art has a problem that the error in the positional coordinate error between the signal controller and the vehicle is too large to provide an error for a signal violation accident, and in particular, driving excluded from the signal violation accident item when an intersection accident with a traffic light occurs. In the event of various accidents such as negligence accidents, car accidents, and force majeure "accidental accidents," the cause of the accident cannot be objectively reconstructed.

The prior art is to use the navigation system as a vehicle navigation system as a function of the black box to record and provide the signal information for the safe driving of the vehicle and information about the signal violation incident.

However, the related art has a disadvantage in that the range of error information of the signal controller and the vehicle is increased, and in particular, whether or not the driver is obligated to drive an accident in a situation before and after an intersection accident occurs (the driver is required to avoid the accident in an emergency situation in which an accident occurs). There was a problem that it was not possible to objectively reconstruct and prove whether the cause of the accident was a failure or whether the body structure defect such as a sudden accident caused the accident.

In addition, as a conventional technology, a bidirectional vehicle installed at an intersection of Korean Patent Publication No. 10-2006-42441 and entering and exiting an intersection in a two-way vehicle flow information measuring device installed at a predetermined distance from a traffic signal control device for controlling traffic of the vehicle. It is to detect the flow more precisely and to transmit the information to the traffic signal control device accurately.

In addition, the number of vehicles per unit time, vehicle speed and occupancy time of the waiting queue of the vehicle entering the intersection, as well as the number of vehicles per unit time for the blockage of the vehicle entering the intersection, vehicle speed and occupancy time, etc. It is to accurately reflect the signal cycle of the traffic signal control device in real time by measuring accurate bidirectional vehicle flow information of vehicles flowing in both directions.

In addition, by measuring the bi-directional vehicle flow information of all intersections obtained through the bi-directional vehicle flow information collection device installed at the intersections in a wider range and providing it to the host of the center, the accurate bi-directional vehicle flow information of several intersections is used as basic data. It decides the signal cycle of all intersections and provides drivers with vehicle flow information of the entire intersection, so that it can be used as basic data to avoid traffic jams and get to the desired destination, so that traffic can be smoothed.

The prior art measures and collects flow information of a vehicle using a bidirectional vehicle flow information measuring device and a bidirectional vehicle flow information collecting device, and reflects the signal cycle of the traffic signal control device in real time with the collected information. However, the prior art has a problem that it is not easy to control the traffic flow in real time with a complex configuration for the detection of the vehicle.

On the other hand, traffic on the road requires preferential traffic compared to other vehicles, that is, a civil service car carried by the president or the head of state, an ambulance for transporting emergency patients, or a fire truck dispatched for fire suppression. There is an urgent need for a method to secure a safe and quick priority traffic by obtaining signals by automating an unmanned system, and also to block a retirement vehicle for crime.

In consideration of this, the emergency vehicle traffic control system of Korean Patent Publication No. 10-2006-0107262 has been invented.

The prior art includes a remote control provided in the emergency vehicle for controlling the wireless transmission of the control signal to the traffic signal controller; The traffic signal controller is provided with the control signal sent from the remote control to control the traffic signal and the signal control for transmitting the control situation to the traffic control server; including a priority traffic traffic configured and operated as described above The control system, by using the remote control provided in the emergency vehicle can turn on and off the traffic signal located in the direction of the road, so as to ensure safe and quick movement. In particular, the traffic control server can track the vehicle equipped with the remote control in real time to identify the surrounding traffic situation and cope efficiently, which has a useful advantage of minimizing the confusion and congestion.

However, the above-mentioned technique is a method of measuring the direction vehicle flow information of vehicles flowing in both directions between the intersection and the intersection of the frontal vehicle through the registration information of the vehicle navigation system because the satellite control is not well controlled. In order to satisfy this condition, the system must be able to operate the system to open the forward passage in the city. It is necessary to operate a signal system that opens in advance to secure the way out of the emergency vehicle by operating the route securing method to remove the stagnant car from the front and forward stages of the vehicle. There is no way to open The dots were.

In addition, unfair administration due to the imposition of traffic penalties regardless of intentionality was taken with camcorders and digital cameras, which guarantee the security of police officers, without considering the driver's driving situation about the intersection tail bites of road vehicles. There is a problem in that reliability of disposal is required, and in particular, there is a waste of human resources and unscientific rules for screening and disposing of municipal waste.

On the other hand, at sea, the route of the ship is set based on the inaccurate track position coordinates and the corrected coordinates of the ship operator. There was a problem of collision with the ships coming from different directions when hitting the designated route that could be lost due to weather change.

In addition, the plane and the altitude of the plane to achieve the ground must be correctly set or recognized to achieve a safe flight of the route, speed, altitude, etc. In the case of deviation from the unauthorized path, there is a problem of flying safety accidents that collide with each other in the sky. have.

In view of the above problems, the present invention collects vehicle information and vehicle information traveling on a road from vehicle navigation system to a traffic control center through a high-speed Internet communication network, and retrieves and retrieves the traffic signal controller from a traffic signal controller searcher. The purpose is to control the vehicle signal and the pedestrian signal more efficiently by data calculation of the walking amount information of a pedestrian.

In addition, the present invention is to correct the position coordinates of the registered vehicle with the coordinate correction device so that the error information is minimized in the vehicle information sent to the traffic control center through the high-speed Internet communication network from the navigation device of the vehicle driving the road floating information and flow information Another purpose is to efficiently control vehicle signals and pedestrian signals by calculating data of vehicle information input from the traffic control center set to a specific position coordinate and pedestrian walking information collected from the traffic signal controller searcher.

In addition, the present invention is an intermediate for transmitting and receiving data between the navigation device and the traffic signal controller in the vehicle to more efficiently control the vehicle signal and the pedestrian signal by calculating the amount of walking information of the pedestrian retrieved by the traffic signal controller searcher The traffic control center, which establishes a traffic control center as a medium, constitutes a 1: 1 1: 1 active signal management operation system, which is a traffic control center that manages the signal management operation system, and this traffic control center is a traffic control center. The traffic management department of the jurisdiction police station, which has jurisdiction over the jurisdiction of the jurisdiction, and the traffic police department, the district police office, which is the superior authority of the jurisdiction police station under the jurisdiction of the traffic control department, the local police office, the jurisdiction police station under the jurisdiction of the local police office, and again the jurisdiction police station The traffic control department under the jurisdiction of the police station, and the traffic control department again with the traffic control center under the jurisdiction of the traffic control department. In addition, the traffic control center may be a traffic signal controller that manages the traffic control center, and the traffic signal controller may be one or more in order to automatically control the traffic lights according to the traffic volume. The place is organically communicated to the traffic signal controller to receive the floating information of the vehicle and the flow information of the vehicle traveling on the road from the vehicle's navigation system through the high-speed Ethernet communication network.Then, the position coordinates are clearly set and sent to the traffic control center. It is another object to more efficiently control the vehicle signal and the pedestrian signal by calculating the vehicle information and the walking amount information of the pedestrian searched and collected by the traffic signal controller searcher.

In addition, the present invention collects the traffic volume of the area where the traffic signal controller is installed by transmitting and receiving data between the traffic signal controller and the vehicle navigation system in response to the vehicle, and transmits the traffic volume to the traffic control center to provide and use the traffic situation information. The system operation can be made to measure the direction of vehicle flow information of vehicles flowing in both directions between the intersection and the intersection to secure the signal cycle for the emergency vehicle to pass the signal cycle of the traffic signal control device. In order to meet this condition, the emergency vehicle system must be opened to operate the emergency vehicle system. Operate signaling system to open ahead in advance to secure passage There is still another object to so.

In another aspect, the present invention is the driver's negligence of the driver when the accident occurs at the intersection with the traffic light, body failure. In case of force majeure accident such as sudden accident, digital vehicle operation recorder (driving information, failure information, defect information) and camera for recording internal and external images in case of accident, so that the cause can be proved objectively. Another purpose is to have a data collection capability of the rescue function operation to reduce the positional error deviation of the vehicle and analyze the cause of the accident by means of a microphone and a speaker receiving emergency action information.

In addition, when an emergency vehicle requests priority traffic, the traffic signal controller and traffic signal associated with the traffic control center automatically control traffic signals based on the registered information of the vehicle so that priority traffic is possible. It is another purpose for the traffic signal to automatically control the traffic lights when there is a need to pass at the same time to open the road ahead) and to restrict the traffic of the vehicle.

In addition, the present invention is not only on the road, but also at sea, when the ship's operating route is requested to depart from the port office, if the port is registered and set in advance, the route is set at the satellite coordinates and the lighthouse or apex display point based on the boat position coordinates and correction coordinates. If there is a fear of colliding with a ship entering from a different direction or colliding with a ship that is leading from a low note number, or a ship entering from another direction, it is possible to prevent deviation and collision with the algorithm data calculated by calculating the difference between the speeds. There is another purpose.

In addition, the present invention, when ordering the flight route and position altitude when the flight takeoff application to take off the ground, the plane must fly in accordance with the reservation of the route, speed, altitude, etc. by the communication between the control tower and the aviator and leave the authorized set route In this case, it is another purpose to send a warning message about the departure route so as to induce a safe operation to prevent a collision accident.

The intelligent traffic signal control method of the present invention made as described above will be described with reference to the flowchart of FIG. 6.

First, the traffic signal controller 100 detects pedestrian information waiting in the waiting area A in the pedestrian detector 230 installed in the pedestrian traffic light 220 and receives the detected pedestrian information (S100). At this time, the pedestrian detector 230 photographs the standby area A as an image, and transmits the captured image signal to the traffic signal controller 100.

The traffic signal controller 100 analyzes the number of pedestrians from the image from the image of the pedestrian detector 230 (S110).

Image analysis for the number of pedestrians extracts pedestrian information by the pedestrian recognition algorithm in the controller 310. That is, the traffic signal controller 100 compares the initial image of the pedestrian detected by the pedestrian detector 230 installed in the pedestrian traffic light 220 and the photographed pedestrian image with the initial image, and applies an algorithm for comparing and determining the number of pedestrians. to be.

Here, congestion is aggravated when the signal in the congestion direction is opened during congestion, so that congestion can be prevented by opening the congestion direction signal system for each area where congestion does not increase by utilizing congestion information of the signal passing vehicle.

In addition, the traffic signal controller 100 determines that the pedestrian entering the photographing area is a pedestrian substantially passing the crosswalk when the pedestrian entering the photographing area is stopped without moving for a predetermined time in the pedestrian image detected by the pedestrian detector 230.

The pedestrian information is extracted based on the pedestrian information stored in the pedestrian information DB 150 from the captured image. For example, the characteristics of the pedestrian are classified from the pedestrian image, and the presence or absence of the pedestrian is determined according to the classified features.

Therefore, the traffic signal controller 100 recognizes and analyzes the number of pedestrians from the pedestrian image. The pedestrian detector 230 detects the number of pedestrians in both directions of the crosswalk.

In addition, the traffic signal controller 100 collects vehicle vehicle information transmitted from the vehicle navigation apparatus 300 from the vehicle control center 500 at a position where data can be received (S120).

The vehicle control center 500 receives vehicle information from the vehicle navigation apparatus 300 mounted on the vehicle 10 entering the area set on the road, and the vehicle control center 500 transmits the vehicle information to the vehicle navigation apparatus 300. Send information about control and traffic volume.

The communication between the vehicle control center 500 and the vehicle navigation device 300 is made of the ultra-high speed internet communication network 700, and is a radio signal from the mobile communication terminal 400 connected to the input / output device 330 of the vehicle navigation device 300. Can selectively transmit and receive.

The mobile communication terminal 400 performs wireless communication between the vehicle detector 210 and the vehicle navigation apparatus 300 through the repeater 410 of the mobile communication company 600. Furthermore, wireless data transmission and reception through the ubiquitous sensor network USN is also possible between the vehicle detector 210 and the vehicle navigation apparatus 300. Communication through the ubiquitous sensor network (USN) may be a preferred application because it can transmit and receive data in a large space and uses low power.

In addition, the data transmitted from the traffic signal controller 100 to the vehicle navigation apparatus 300 through the vehicle detector 210 includes a signal for a crosswalk or an intersection to which the vehicle 10 equipped with the vehicle navigation apparatus 300 is to pass. The information is expressed by voice, text or graphics through the output device and the display device.

The traffic signal controller 100 is a vehicle installed in a vehicle traffic light 200 corresponding to the vehicle 10 for controlling the traffic signal, that is, in FIG. 4, for controlling the traffic signal. The vehicle information is received from the vehicle 10 in the road area set by the detector 210, and the received vehicle information is input to the traffic signal controller 100.

Therefore, the traffic signal controller 100 receives information about the entry of the vehicle from the vehicle navigation apparatus 300 and analyzes the number of individuals of the vehicle. At this time, the controller 110 inputs and outputs various information data about the vehicle from the vehicle information DB 140.

The traffic signal controller 100 extracts the number of pedestrians from the image signal of the pedestrian detector 230, and extracts the number of vehicles of the vehicle from the vehicle detector 210 to control the optimal information in real time through a data calculation algorithm. After calculating the value, the traffic control signal is output to the vehicle traffic light 200 and the pedestrian traffic light 220 (S140).

At this time, the controller 110 of the traffic signal controller 100 controls the traffic signal related to turning on and off the pedestrian traffic light 220 and the vehicle traffic light with reference to the cycle and time of the traffic signal set in the signal control DB 130. Is done. The cycle and time of the traffic signal are the lighting cycle and time of the green traffic light for the passage of the corresponding vehicle or pedestrian and the red traffic light for the waiting of the vehicle or pedestrian.

The control of the traffic signal may be divided into several control cycles set in the signal control DB 130. For example, when the number of vehicles on the road is larger than the set number of people and the pedestrian's atmosphere is low, the lighting time for the traffic light of the vehicle 200 is turned on in proportion to the number of vehicles, and when the traffic jams, If opened, congestion increases, so that the traffic information of the traffic passing through the vehicle and the lighting time for the passage of the pedestrian traffic light 220 is long in proportion to the number of pedestrians when the vehicle is less than the set number of individuals on the road and there is a large number of pedestrians. do. In addition, when the number of vehicles on the road is less than the set number of people and the pedestrian's atmosphere is less, the on and off cycles for the passage of the pedestrian traffic light 220 and the driving of the vehicle traffic light 200 are turned on and off at a set cycle, and When the vehicle is larger than the set number of people and there is a large number of pedestrians, the lighting and extinguishing cycles for the passage of the pedestrian traffic light 220 and the driving of the vehicle traffic light 200 are turned on and off at a predetermined cycle.

In the case where the number of individuals of the vehicle and the number of pedestrians are small or large, respectively, the vehicle traffic light 200 may be relatively long or the pedestrian traffic light 220 may be lengthened to correspond to the road conditions or conditions.

In addition, when there are a lot of vehicles in one direction on the road, the corresponding vehicle signal lights 200 are kept on to lengthen to facilitate the communication of vehicles, and when there are a large number of waiters at any one crosswalk, pedestrian traffic lights 220 The longer the lighting of the pedestrians to facilitate the communication to reduce the waiting time of the pedestrians.

Next, at night, for example, between 12 am and 5 am, if there is little pedestrian traffic and traffic is not frequent, the traffic signal controller 100 may prolong the lighting period of the vehicle traffic light 200. give.

At this time, if the pedestrian detector 230 detects the pedestrian while the vehicle signal 200 continues to be turned on, the pedestrian signal 220 lights up in green and the vehicle signal 200 lights up in red for a predetermined time. . This will solve the problem that the traffic signal controller can cause a safety accident for vehicles and pedestrians by giving a blinking yellow traffic light, which is an unprotected signal at night.

Accordingly, the traffic signal controller 100 may control the lighting time of the traffic light to vary according to the number of pedestrians or vehicles.

On the other hand, when operating an emergency vehicle system that requires traffic, the road to proceed to enter an emergency vehicle must be open, so in order to satisfy the opening of the road, the way to secure the outgoing road to pull out the stagnant car from the front step of the emergency vehicle. In order to ensure the exit of emergency vehicles by the operation of the signal system to be opened in advance to operate.

This system measures the direction vehicle flow information of vehicles flowing in both directions between the intersection and the intersection of the front blocked vehicle, and the system operation is performed to secure the signal cycle for the emergency vehicle to pass the signal cycle of the traffic signal control device. .

Meanwhile, the traffic signal controller 100 transmits and shares the control information as wired or wireless data to one or more traffic signal controllers installed adjacent to each other. The traffic volume of the pedestrian and the pedestrian information can be used to maintain a smooth and consistent traffic signal system (S150).

In other words, when congestion signals are opened, congestion is increased, and congestion traffic can be prevented by maintaining a smooth and consistent traffic signal system by using congestion information and pedestrian information.

In addition, the traffic signal control information of the plurality of traffic signal controller 100 is transmitted to the traffic control center 500 to be collected (S160).

The traffic control center 500 stores the traffic information and the traffic volume in the database 540 from the traffic signal control information collected by the plurality of traffic signal controllers 100 so as to utilize the traffic volume information with more accurate location information. (S170)

In addition, the traffic control center 500 may transmit and receive data directly from the traffic signal controller 100 or collect traffic signal control information of each traffic signal controller 100 through an adjacent traffic signal controller 101.

In the intelligent traffic management control method of the present invention, in the flowchart of FIG. 7 showing more precise geographic information provision and traffic volume collection and control, the vehicle navigation apparatus 300 in the vehicle 10 includes a GPS receiver 320 and a high-speed Internet. Receive the position coordinates containing the error from the traffic control center 500 through the communication network 700 (S200).

The vehicle navigation apparatus 300 transmits and receives a position coordinate including an error to the vehicle detector 210, and the vehicle detector 210 transmits the received position coordinate to the traffic control center 500 (S210).

The traffic control center 500 which receives the position coordinate including the error generates the corrected position coordinate. That is, since the traffic signal controller 100 is a fixedly installed point, the correct position coordinate of the vehicle navigation apparatus 300 is corrected after comparing the exact position coordinate thereof with the position coordinate received from the vehicle navigation apparatus 300 (S220).

The traffic control center 500 transmits the corrected position coordinates to the vehicle navigation apparatus 300 of the corresponding vehicle via the vehicle detector 210 through the high speed internet communication network 700 (S230).

Therefore, the traffic control center 500 determines the exact position of the vehicle navigation apparatus 300 mounted on the vehicle 10 that has transmitted and received data (S240).

This causes the traffic control center 500 to correct the error component included in the GPS information of the high speed internet communication network 700 received by the GPS receiver 320 so that the vehicle navigation device 300 is provided to the vehicle navigation device 300. .

The traffic signal controller 100 and the vehicle navigation apparatus 300 transmit the traffic volume information including the more accurate location information to the traffic control center 500, so that the traffic control center 500 is connected to the exact location information of the vehicle 10. Traffic volume information can be used. In addition, the traffic control center 500 may utilize more precise and accurate location information when tracking of the corresponding vehicle 10 is required.

Furthermore, the vehicle navigation apparatus 300 can display the geographic information based on the corrected position coordinates with the display device 340, and can visually express the traffic situation or the traffic information of the road where the vehicle is located. Allows the driver to recognize accurate information about the operation of the vehicle.

Meanwhile, in the flowchart of FIG. 9, the vehicle navigation apparatus 300 receives information on a traffic signal and information on a traffic volume from the traffic control center 500 (S300).

The vehicle navigation device 300 displays information on the received traffic signal on the display screen of the display device 340. That is, in FIG. 8, a screen displaying the geographic information of the vehicle navigation apparatus 300 in which the information of the vehicle traffic light 200 which is scheduled to pass within a predetermined distance in front of the vehicle 10 on which the vehicle navigation apparatus 300 is mounted travels on the road. It is to be expressed as a traffic light (301) visible to. For example, if the front vehicle traffic light 200 is a red traffic light, the red traffic light is also turned on the display screen, and if the vehicle traffic light 200 is the green traffic light, the green traffic light is also lit on the display screen.

In addition, the vehicle navigation device 300 outputs a guide voice so that the driver can easily recognize the information of the vehicle traffic light 200 of the crosswalk or intersection to be passed through hearing. That is, in the same way as the traffic light 301 displayed on the vehicle traffic light 200 and the display screen, the voice "Current green light is on" or "Current red light is on" is mounted on the vehicle navigation device 300. Output through the speaker.

In addition, the vehicle navigation apparatus 300 may guide the driver to recognize the lighting time or the extinguishing time of the green traffic light and the red traffic light of the vehicle traffic light 200.

In addition, the vehicle navigation apparatus 300 compares and determines the current vehicle traveling speed by using the information on the traffic signal received from the traffic control center 500 and the information on the traffic volume (S320).

The vehicle navigation apparatus 300 predicts that the green traffic light is changed to a red traffic light when the traffic light of the preceding vehicle is heavy even when the vehicle traffic light 200 in front of the vehicle is going to be turned on by the green traffic light and the vehicle 10 is at an intersection or the like. It guides whether the passage of the crosswalk is possible (S330).

This is based on a comprehensive analysis of traffic volume information and control information of a vehicle traffic light 200 regarding a vehicle that has passed or is passing through an intersection or pedestrian crossing before the intersection or pedestrian crossing to which the vehicle 10 is to pass, and the driving speed of the current vehicle 10. The comparison and the determination is to guide the driver of the vehicle 10 whether it can pass. Information about whether or not it is possible to pass through the road in heavy traffic, such as commute time, frequent delays or heavy traffic, the driver only sees the traffic light (200) to cross the intersection or crosswalk (aka, "tail It is intended to promote concession driving and traffic safety by inducing not to bite.

Accordingly, the driver may drive the vehicle safely by recognizing the traffic lights and the like displayed on the vehicle navigation apparatus 300 and information on whether the intersection or the crosswalk can be passed.

In addition, the driver may check in real time with the visible traffic signal 301 of the vehicle navigation apparatus 300 without looking at the traffic light 200 even if a vision obstacle occurs because the front view is obstructed. Even without looking at (200), since the traffic light 200 information is replaced, safe driving can be realized.

On the other hand, when a traffic accident occurs at the intersection with the traffic light 200, the driver may be notified of the violation of the instruction of the traffic light 200 equalization, and the fact information may be stored to secure objectivity and output if necessary. It is.

In addition, the vehicle navigation apparatus 300 photographs internal and external images at the time of an accident with a camera that can objectively prove the driver's fault of operation when a traffic accident occurs on the road and the cause of the vehicle's failure as a cause of a vehicle (accidental accident). The microphone is designed to store crash site impact noise in case of an accident, and the speaker is capable of receiving first aid information.
